Analytical Standard Valerophenone CAS 1009-14-9 GC Purity 99.9% Reference Liquid

A quantitative method for an aromatic ketone is only as reliable as the standard used to calibrate it. This analytical grade of valerophenone (CAS 1009-14-9) is prepared from the high purity production stream, ampouled under argon and characterised by GC with flame ionisation detection and by GC-MS for identity, so a laboratory can build a calibration curve and document traceability without spending weeks on internal characterisation.

The certificate reports purity by area normalisation, every impurity peak above 0.01 percent, water content and the retention index on a standard non polar column. That level of detail is what an ISO 17025 audit or a method validation report requires, and it is why laboratories working on residual ketone analysis, reaction monitoring or fragrance quality control keep this material as a house standard.

• Purity 99.9% by GC area normalisation: a clean calibration point for quantitative methods and reaction monitoring
• Impurity peaks identified per lot: every peak above 0.01% listed so interference is known before the method is validated
• Identity confirmed by GC-MS: verifies the main peak against the reference spectrum and rules out isomeric ketones
• Argon filled amber ampoules: no oxidation or colour drift between analyses, even over months
• Retention index reported: transferable between instruments and columns for method development
• Water 0.05% maximum: stable retention times and no hydrolysis in derivatisation steps

Used to calibrate GC and GC-MS methods for valerophenone in reaction mixtures, fragrance concentrates and residue studies, as an internal standard in quantitative ketone analysis, and as an identity reference in raw material incoming inspection.

A working solution is normally prepared at 0.1 to 1 mg/mL in a solvent such as methanol or isooctane, stored at 2 to 8 degrees C in a sealed vial and used within one month. Our analytical note gives an oven programme on a 30 m 5 percent phenyl column with the expected retention window and response factor.

Packed in 100 mL and 500 mL amber glass bottles with PTFE lined caps, argon filled and foam packed in cartons for air freight. Each container carries lot number, purity, packaging date and the storage instruction.

Store at 2 to 8 degrees C under argon, protected from light, and allow the container to reach room temperature before opening to avoid condensation. Shipments leave within 7 to 15 working days with COA and chromatogram attached.

Every lot ships with a Certificate of Analysis, the GC chromatogram, the GC-MS identification report and the retention index. A retention sample is stored under argon for 36 months.

We can provide a statement of traceability and the measurement uncertainty for the assigned purity. Custom mixtures of valerophenone with related ketones for selectivity testing can be prepared to order.
