UOP 262-99 is a laboratory test method for measuring phenols and thiophenols in petroleum products by spectrophotometry. For buyers and technical teams, it provides a standardized way to evaluate these sulfur- and oxygen-containing compounds where their presence may affect product quality, handling, or downstream processing. As a UOP method, it is suited to petroleum testing environments that need consistent analytical documentation and comparable results across samples. It is especially relevant when laboratories need a clear method reference for routine review, investigation work, or product comparison.

What is UOP 262-99?

UOP 262-99 is an analytical UOP test method focused on the spectrophotometric determination of phenols and thiophenols in petroleum products. Its purpose is to support laboratory measurement of specific aromatic compounds that may be present in refinery or fuel-related samples. Because the method is tied to spectrophotometry, it fits into instrumental laboratory workflows where controlled, repeatable analysis is important. This makes UOP 262-99 a practical method reference for organizations that need a defined approach to compound evaluation in petroleum matrices.

Where is UOP 262-99 used?

UOP 262-99 is commonly used in petroleum laboratories, refinery QA/QC programs, and analytical chemistry groups that review product composition or contamination concerns. It may also be useful for fuel testing personnel, petroleum specialists, and technical reviewers who need a recognized method for assessing phenols and thiophenols in samples. In practice, it supports laboratory work tied to sample evaluation, product verification, and technical documentation when these compounds are of interest. It is a good fit for organizations that rely on UOP methods for routine or investigative analysis.

Why is UOP 262-99 important?

UOP 262-99 matters because it gives laboratory teams a consistent analytical basis for checking phenols and thiophenols in petroleum products. That helps support product comparison, quality control, and clearer technical review when sample behavior or composition needs to be understood. For refinery and laboratory users, a defined method can improve result consistency across different batches and testing cycles. It also helps preserve documentation quality when analytical findings are reviewed by QA/QC, process, or product quality teams.
