Chemical Structure

5-Methylcytosine CAS 554-01-8 chemical structure

Description

The occurrence of 5-Methylcytosine is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Methylcytosine (CAS 554-01-8), a certified reference material (molecular formula C5H7N3O, MW 125.13 g/mol) for analytical method development and quality control.

Owing to an amide group, a hydroxyl group, an ether linkage, 5-Methylcytosine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 125.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5-Methylcytosine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
