Chemical Structure

Sodium (S)-4-carboxy-2-(4-(((2,4-diaminopteridin-6-yl)methyl)(methyl)amino)benzamido)butanoate CAS 15475-56-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium (S)-4-carboxy-2-(4-(((2,4-diaminopteridin-6-yl)methyl)(methyl)amino)benzamido)butanoate.

CATO supplies Sodium (S)-4-carboxy-2-(4-(((2,4-diaminopteridin-6-yl)methyl)(methyl)amino)benzamido)butanoate (CAS 15475-56-6), a certified reference material (molecular formula C20H21N8O5Na, MW 476.43 g/mol) for analytical method development and quality control.

Structurally, Sodium (S)-4-carboxy-2-(4-(((2,4-diaminopteridin-6-yl)methyl)(methyl)amino)benzamido)butanoate (C20H21N8O5Na) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 476.43 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Sodium (S)-4-carboxy-2-(4-(((2,4-diaminopteridin-6-yl)methyl)(methyl)amino)benzamido)butanoate 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.
