Salbutamol Impurity 100 CAS 16475-90-4

Description

Compared with other compounds in its class, the molecular weight of 194.18 g/mol gives Salbutamol Impurity 100 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Salbutamol Impurity 100 (CAS 16475-90-4) is a certified pharmaceutical impurity reference standard with the molecular formula C10H10O4 and a molecular weight of 194.18 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Salbutamol Impurity 100 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Salbutamol Impurity 100 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.
