L-Phenylalanine (CAS 63-91-2) sourcing notes: practical points for Industrial Chemicals
A lot of buyers assume L-Phenylalanine (CAS 63-91-2) is a buy-and-it-works item. In Industrial Chemicals it almost never is. The compatibility rhythm and dosing usually decide the final result, so this page unpacks exactly those pieces.

Key physical data: molecular formula C9H11NO2, molecular weight 165.08 g/mol, CAS 63-91-2, melting point 283 °C. Sourced from public chemical databases such as PubChem, ChemSpider and the CAS Registry; the CAS number is the authoritative registry identifier. Purity and packaging follow the batch COA and order confirmation.
Let's get the mechanism first
It's simpler than it looks:Industrially, the value of L-Phenylalanine (CAS 63-91-2) is rarely on the spec sheet — it is whether it stably meets your process window. In Industrial Chemicals, its purity, impurity profile and batch consistency usually matter more than a single 'assay' number, because what really moves the finished result is often the ignored impurities and physical properties. Comparable grades:
- L-1,2,3,4-TETRAHYDRO-QUINOLINE-2-CARBOXYLIC ACID HYDROCHLORIDE (CAS 63430-98-8)：a comparable grade often evaluated alongside。
- L-1,2,3,4-Tetrahydroisoquinoline-3-carboxylic acid (CAS 74163-81-8)：a comparable grade often evaluated alongside。
- L-1,2,3,4-TETRAHYDRONORHARMAN-3-CARBOXYLIC ACID (CAS 42438-90-4)：a comparable grade often evaluated alongside。
- L-1-Boc-Nipecotic acid (CAS 88495-54-9)：a comparable grade often evaluated alongside。
- L-1-CBZ-PIPECOLINAMIDE (CAS 61703-39-7)：a comparable grade often evaluated alongside。
How to get the choice right
- The one I weigh most: Define the end use and process window first, then work back to required purity and impurity limits — not the other way around.
- Check compatibility with other materials in the system; run a trial when unsure.
- Match packaging and feeding method to on-site equipment so the material is usable on arrival.
- Retain samples of critical lots and run third-party checks; do not rely on the supplier COA alone.
What newcomers overlook
Comparing price but not impurity profile: same assay with different impurities can yield wildly different results.
Skipping samples and scaling up: going straight to volume most often fails on compatibility.
Ignoring transport and storage: most 'arrived-dead' cases trace back to loose handling.
The ones you'll likely ask
How do I compare value across suppliers of L-Phenylalanine at the same spec?
Don't just compare price per kg — compute usable yield. Purity, batch consistency and documentation completeness all affect what actually makes it through your QC; line up the key COA values across vendors before opening the price conversation.
Signal to switch suppliers of L-Phenylalanine?
If key impurities drift >10% between consecutive lots, or two on-site re-tests in a row fail, start qualifying a second source — don't wait for a line stoppage.
How often should the L-Phenylalanine MSDS be refreshed, and is it a regulation?
MSDS has no fixed refresh cadence, but it should be revisited whenever the regulation, customer standard, or the molecular/impurity profile changes; an annual version check keeps arrival documents from going stale.
What is the molecular formula and weight of L-Phenylalanine?
For L-Phenylalanine, the molecular formula is C9H11NO2 and molecular weight about 165.08 g/mol (CAS 63-91-2). These are published physical properties; exact purity, specification and packaging follow the batch COA and order confirmation.
