Chemical Structure
Description
As a certified reference material (CRM), Benzeneacetic acid, α-(hydroxymethyl)-4-(methoxycarbonyl)- 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.
Benzeneacetic acid, α-(hydroxymethyl)-4-(methoxycarbonyl)- (CAS 2822643-05-8) is a high-purity analytical reference standard with the molecular formula C11H12O5 and a molecular weight of 224.21 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Benzeneacetic acid, α-(hydroxymethyl)-4-(methoxycarbonyl)- is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.21 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.
