Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 765-69-5 C9LG5VP01C 2-Methyl-1,3-cyclopentanedione 2-Methylcyclopentane-1,3-dione EINECS 212-153-2 EC 212-153-2 UNII-C9LG5VP01C.
765-69-5 C9LG5VP01C 2-Methyl-1,3-cyclopentanedione 2-Methylcyclopentane-1,3-dione EINECS 212-153-2 EC 212-153-2 UNII-C9LG5VP01C (CAS 765-69-5), molecular formula C6H8O2 and molecular weight 112.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H8O2, 765-69-5 C9LG5VP01C 2-Methyl-1,3-cyclopentanedione 2-Methylcyclopentane-1,3-dione EINECS 212-153-2 EC 212-153-2 UNII-C9LG5VP01C contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 112.13 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).
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), 765-69-5 C9LG5VP01C 2-Methyl-1,3-cyclopentanedione 2-Methylcyclopentane-1,3-dione EINECS 212-153-2 EC 212-153-2 UNII-C9LG5VP01C 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.
