5'-O-DMT-Thymidine

What it means: Purity indicates the proportion of the target compound relative to total mass. A purity of ≥ 98.0% means that at least that percentage of the material is the stated compound, with impurities (residual solvents, salts, or related by-products) accounting for the remainder.

Why it matters:

• Enzyme kinetics and Michaelis–Menten analyses require accurate substrate concentrations — lower purity introduces systematic error into calculated K_m and V_max values.
• In vitro pathway reconstitution assays can be confounded by trace impurities that act as inhibitors or competing substrates.
• Isotopic labeling or mass spectrometry applications demand high purity to minimise background signal from related compounds.

How to interpret here: This crystalline nucleoside analog is supplied at ≥ 98.0%, verified by HPLC. A Certificate of Analysis (COA) with the measured purity value is available for download on the product page. If your assay requires a tighter specification, custom analytical packs can be requested via the Customization tab.

What it means: Form refers to the physical state in which the compound is supplied. Crystalline powder indicates the material has been freeze-dried from solution, removing solvent to yield a dry, stable solid.

Why it matters:

• Crystalline powder typically offers longer shelf-life and better thermal stability during transit compared with pre-dissolved solutions.
• You control the reconstitution solvent, concentration, and buffer composition — important for assays with strict ionic strength or pH requirements.
• Aliquoting from a dry powder allows preparation of multiple independent stock solutions to minimise freeze-thaw cycles.

How to interpret here: Receive as Crystalline powder; dissolve in your buffer of choice immediately before use. For CoA thioester derivatives, prepare working solutions on ice and use promptly to avoid hydrolysis. Recommended storage: 2–8 °C.

What it means: Molecular Weight (MW) is the mass of one mole of the compound, expressed in g/mol. For this product the MW is 544.60 g/mol.

Why it matters:

• Used to calculate the molar concentration of working solutions from a weighed mass — critical for enzyme kinetics where substrate concentration must be accurately defined.
• For salt forms (e.g., lithium, sodium), the listed MW is the free-acid equivalent. Use this value when normalising across different salt variants of the same compound.
• In LC-MS applications, the MW informs the expected parent ion m/z and helps confirm compound identity in complex matrices.

How to interpret here: Use 544.60 g/mol to convert between mass (mg) and moles when preparing stock solutions. For nucleoside analogs supplied as salt forms, the free-acid MW is provided so you can normalise accurately regardless of the counterion present.

What it means: Activity describes the compound's functional class. Nucleoside Analog indicates this compound is a chemically modified version of a naturally occurring nucleoside, where one or more positions have been altered to change biological or chemical properties.

Why it matters:

• Nucleoside analogs can act as competitive inhibitors, chain terminators, or alternative substrates for polymerases, kinases, and nucleotidases.
• The specific modification (5'-iodo, 5'-azido, DMT-protected, TIPS-protected) defines compatibility with solid-phase synthesis, click chemistry, or enzymatic assays.
• Activity classification helps researchers identify whether this compound is suited for synthesis applications, biochemical probing, or both.

How to interpret here: This compound is a Nucleoside Analog. Select it when you need a chemically modified nucleoside building block for oligonucleotide synthesis, mechanistic enzyme studies, or bioconjugation via functional handles such as azide or halogen groups.

What it means: Source indicates the manufacturing origin. Synthetic means the compound was produced via chemical synthesis rather than biological or fermentation-based processes.

Why it matters:

• Synthetic production enables precise control over chemical structure, stereochemistry, and isotopic labelling — important for mechanistic and tracer studies.
• Batch-to-batch chemical consistency is typically tighter with synthetic routes, supporting reproducible results across experiments.
• For nucleoside analogs, Synthetic origin confirms defined protecting-group chemistry and absence of biological matrix carryover.

How to interpret here: This product is Synthetic. The stated purity and COA documentation reflect quality control of the synthetic process. Lot-specific analytical data are available on request.

What it means: Shipping indicates the cold-chain packaging method used to maintain compound integrity during transit. Ambient temperature (styrofoam + ice gels) means the product is dispatched with ice packs inside insulated styrofoam packaging to keep it cool throughout delivery.

Why it matters:

• CoA thioester and nucleoside analog compounds can degrade if exposed to elevated temperatures during shipping — cold chain packaging protects against thermal degradation.
• Knowing the shipping method helps you plan receipt: have your −20 °C (CoA thioesters) or 2–8 °C (nucleoside analogs) storage ready at time of delivery.
• Cold chain also protects the lyophilized/crystalline physical form from moisture condensation that can reduce stability.

How to interpret here: This product ships via Ambient temperature (styrofoam + ice gels) at ambient temperature in insulated packaging with ice gels. Upon receipt, transfer to the recommended long-term storage temperature immediately. Check the packaging integrity and note the condition on arrival; contact BioHippo if any concerns arise.
