Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 134052-66-7 M725GQ103A 4-Carboxy-3-hydroxyphenylglycine Benzeneacetic acid, alpha-amino-4-carboxy-3-hydroxy-, (+-)- Benzeneacetic acid, alpha-amino-4-carboxy-3-hydroxy- (+-)-alpha-Amino-4-carboxy-3-hydroxybenzeneacetic acid 4-Chpgly alpha-Amino-4-carboxy-3-hydroxybenzeneacetic acid UNII-M725GQ103A.

134052-66-7 M725GQ103A 4-Carboxy-3-hydroxyphenylglycine Benzeneacetic acid, alpha-amino-4-carboxy-3-hydroxy-, (+-)- Benzeneacetic acid, alpha-amino-4-carboxy-3-hydroxy- (+-)-alpha-Amino-4-carboxy-3-hydroxybenzeneacetic acid 4-Chpgly alpha-Amino-4-carboxy-3-hydroxybenzeneacetic acid UNII-M725GQ103A (CAS 134052-66-7) is a high-purity analytical reference standard with the molecular formula C9H9NO5 and a molecular weight of 211.17 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 134052-66-7 M725GQ103A 4-Carboxy-3-hydroxyphenylglycine Benzeneacetic acid, alpha-amino-4-carboxy-3-hydroxy-, (+-)- Benzeneacetic acid, alpha-amino-4-carboxy-3-hydroxy- (+-)-alpha-Amino-4-carboxy-3-hydroxybenzeneacetic acid 4-Chpgly alpha-Amino-4-carboxy-3-hydroxybenzeneacetic acid UNII-M725GQ103A is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
