Selecting Tyrosine: role, specs and pitfalls in Industrial Chemicals
A lot of buyers assume Tyrosine (CAS 60-18-4) 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.
How it works
Its role in one sentence:Industrially, the value of Tyrosine (CAS 60-18-4) 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。

Purity and packaging follow the batch COA and order confirmation.
Sourcing & incoming-inspection points
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.
Don't trip on these
- 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.
A few things people ask
When buying Tyrosine, which batch documents should I expect?
Standard flow: COA with each shipment, MSDS and TDS on request; if you have a target spec or customer acceptance criteria, list the key limits up front — the supplier will match to your grade, which beats a generic COA.
What should I compare between different batches of Tyrosine?
Beyond assay, the impurity profile and batch-to-batch consistency matter most — residual solvent, colour, heavy metals can shift significantly at the same nominal purity, and that is what moves the finished result. Hold samples of critical lots for third-party checks.
What usually goes wrong with Tyrosine in transport and storage?
Most 'arrived-dead' cases trace back to loose handling: moisture, over-temperature, or commingling. Keep sealed packaging in a cool, dry store, and verify lot numbers and arrival temperature before dosing.
What is the molecular formula and weight of Tyrosine?
For Tyrosine, the molecular formula is C9H11NO3 and molecular weight about 181.07 g/mol (CAS 60-18-4). These are published physical properties; exact purity, specification and packaging follow the batch COA and order confirmation.
