Phthalic-3,4,5,6-d4 Acid CAS 87976-26-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Phthalic-3,4,5,6-d4 Acid.

Phthalic-3,4,5,6-d4 Acid (CAS 87976-26-9), molecular formula C8H2D4O4 and molecular weight 170.16 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H2D4O4, Phthalic-3,4,5,6-d4 Acid contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 170.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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), Phthalic-3,4,5,6-d4 Acid 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.
